Sex robots have become a fast-growing field of development, with Abyss Creations’ ‘Harmony’ RealDoll among the most famous to date.

And now, it looks like Harmony is getting a sister.

On stage at CES for Engadget’s After Hours show, creator Matt McMullen debuted a new personality named Solana – by switching the sexbot’s life-like face for another.

McMullen also revealed he is working on developing male sex bots along with the potential for more gender variation beyond that, and cleared up some misconceptions about how the integration of male anatomy may come to fruition.

During an onstage interview with Engadget Editor-in-Chief Christopher Trout, McMullen explained that the sex robot’s face is designed for versatility.

‘The face is actually modular, the same way that within the app you can change the personality settings and create a separate profile and separate avatar, you’re able to remove and attach a different face to the same robot very easily,’ McMullen said.
